Description
The different phases of tumor immunoediting in vivo were dissected thanks to a murine model of glioma induced by PDGF-B overexpression. We show that low-grade gliomas are highly immunostimulatory and that the adaptive immune system prevents the development of secondary tumor in syngeneic mice. During tumor progression, glioma cells downregulate immunostimulatory genes and the immune infiltrate becomes pro-tumorigenic. We showed that glioma cells are able to progress towards a high-grade phenotype even in immunodeficient mice, albeit more slowly and this progression invariably requires a downregulation of immunostimulatory genes.
